Abstract
The present invention relates to an environmental protection type economic formulation of a coke strength enhancer of water-quenched coke, and belongs to the technical field of coking. The economic formulation comprises a mixture, wherein the mixture is formed by uniformly mixing a surfactant source, a boron source and water according to weight percentages. The economic formulation of the present invention is dissolved in water for quenching the coke, and is mixed and prepared into a dilute aqueous solution with the concentration of 0.01-1%, wherein the prepared dilute aqueous solution can be provided for quenching the coke. When the aqueous solution for quenching the coke is added with the environmental protection type base agent of the coke strength enhancer of the water-quenched coke to quench the coke, the air bubbles are generated by the surfactant source, such that the specific surface area of the coke can be increased, the dust can be effectively adsorbed, the reactivity of the coke can be reduced, the strength of the coke after the reaction can be improved, the moisture content of the coke can be reduced, and the discharge amount of the harmful steam can be substantially reduced.
Description
Technical field
The present invention relates to the economic formulation of a kind of environment-friendly type water quenching coke strenth toughener, belong to the coking technology field.
Background technology
The extinguishing technique that coke production is follow-up requires to make red-hot coke fast cooling, is convenient to transportation and storage.The quenching technology is divided into two kinds of dry method and wet methods, and dry coke quenching has the effect that improves coke quality, environmental protection, recovery heat energy, but because investment is high with working cost, also is difficult to popularization in the short period of time.Wet putting out is the quenching technology that generally adopts at present; The advantage of wet quenching is that investment and process cost are low; Management is simple; Shortcoming is to reduce coke strenth and moisture height and unstable after the quenching, and red-hot coke sprays at water and produces the water vapour that is entrained with a large amount of dust, phenol, sulfide etc. in the quick process of cooling simultaneously, causes environmental pollution and thermal pollution.Along with the maximization of blast furnace and the raising of combustion intensity; The specification of quality of blast furnace STRENGTH ON COKE is increasingly high; And the coking coal quality has downtrending year by year; The coal of coking coal, quality occur than great fluctuation process, and the coke quality of producing is difficult to satisfy the large blast furnace strengthening smelting, further improves the requirement of coal powder injection ratio, and high-quality caking coal is fewer and feweri to require increasingly high contradiction serious day by day with coke quality.And the global pay attention to day by day to environment protection makes that coal chemical enterprise faces immense pressure, has jeopardized the Sustainable development of coking and metallurgy industry.At present wet put out to have in the technology still adopt the traditional water quenching, have above-mentioned problem demanding prompt solution; The passivator technology that adopts is arranged, and postreaction strength of coke has raising, but environmental influence is not improved, and especially the blast furnace effect is not obvious, and coke ratio does not obviously reduce; Useful air film coke quenching agent technology, environmental influence there is improvement, coke quality has raising, but exists coke cold and hot index increase rate less, and the blast furnace effect is unstable, the problem that application cost is high.
Summary of the invention
The objective of the invention is for overcoming the weak point of above-mentioned prior art, provide a kind of environment-friendly type water quenching coke strenth toughener economic formulation, this economic formulation comprises: the mixture that surfactant source, boron source, water mix by weight percentage.This formulation is dissolved in to be hybridly prepared into concentration in the coke quenching water be that the dilute aqueous soln of 0.01-1% gets final product quenching.When adding the coke quenching water solution quenching of the basic agent of a kind of environment-friendly type water quenching coke strenth toughener; The bubble that surfactant source produces can increase the coke ratio surface-area, adsorbs dust effectively; Reduce the reactivity of coke; Improve postreaction strength of coke, reduce the coke water ratio, reduce harmful discharge of steam amount significantly.
The present invention realizes with following technical scheme: the economic formulation of a kind of environment-friendly type water quenching coke table intensity reinforcing agent, it is characterized in that: this economic formulation comprises: the mixture that surfactant source 20-80%, boron source 20-80% mix by weight percentage.
Described surfactant source comprises: Witco 1298 Soft Acid and sodium salt, cetyl trimethylammonium bromide, sodium lauryl sulphate; Described boron source comprises: boric acid, boron cash, borax.The raw material of the economic formulation of environment-friendly type water quenching coke strenth toughener is optional one of which in above-mentioned surfactant source, boron source.
Preferably, the economic formulation of environment-friendly type water quenching coke strenth toughener comprises: surfactant source 40-60%, boron source 40-60% mix by weight percentage.。
The method of use of the economic formulation of environment-friendly type water quenching coke strenth toughener is, these article is dissolved in to be hybridly prepared into concentration in the coke quenching water be that the dilute aqueous soln of 0.01-1% gets final product quenching.When adding the coke quenching water solution quenching of the economic formulation of a kind of water quenching coke surface toughener, the bubble of surfactant source generation can increase the coke ratio surface-area on the one hand, adsorbs dust effectively, reduces the quantity discharged of harmful steam; Boron source in the coke quenching water solution is formed and is filled the boronation film that adds the coke surface duct by the coke surface rapid permeability on the other hand, strengthens coke surface intensity.Thereby reduce environmental pollution and thermal pollution that coke wet quenching causes significantly, effectively improve the post-reaction strength of coke, satisfy the requirement of modern blast furnace and strengthening smelting STRENGTH ON COKE quality.
Advantage of the present invention is: the coke quenching water solution quenching of the economic formulation of using environment-friendly type water quenching coke strenth toughener, and coke reactivity reduces 2-7%; Postreaction strength of coke improves 4-8%; Dust discharge amount reduces more than 95%; The discharge of steam amount obviously reduces; The coke water ratio reduces.Realize the reactivity of remarkable reduction coke, improved postreaction strength of coke, reduced the coke water ratio, reduced harmful discharge of steam amount significantly, realized satisfying the requirement of modern blast furnace strengthening smelting STRENGTH ON COKE quality and the purpose of energy-saving and emission-reduction.
